A sheetrock hammer attachment used in conjunction with a pneumatic hammer operator having a rear body portion and a forward body portion, the forward body portion comprising a threaded bore having its forward end surrounded by a smooth outer sleeve and the rear body portion having an operating switch which activates the vibrating action of the hammer; comprising a hardened steel hammer having a rounded forward head and an elongated shaft extending rearwardly therefrom, the elongated shaft being received in the bore and being operationally connected thereto, a central portion of the head is drilled away to receive a non-magnetic insert containing a smaller cylindrical magnet, the magnet being provided to hold the head of a nail, a plexiglass shield covering the front end of said sleeve and extending forwardly therefrom, a tension spring rotatably affixed to the rear portion of the shield and being wound about the rear portion of the sleeve, and a rotatable nut threadedly connected to the bore adjacent the rear end of the spring for controlling the length of the spring, wherein depressing the switch activates the hammer causing the shield to reciprocate while compressing the spring thereby driving the nail into a panel of sheetrock.
